Embodiment Construction
[0019] Embodiment of automatic test system for yaw drive:
[0020] The yaw drive automatic test system proposed in this embodiment, such as figure 1 As shown, a set of test unit is included, and the test unit includes a first motor, a second motor and an integrated control module. The first motor and the second motor are shaft-coupled through a coupling, butted and fixed, the first motor is used to be controlled by the first yaw driver under test, and the second motor is used to be controlled by the first yaw driver under test; integrated control The module is used to communicate and connect the first yaw driver under test and the second yaw driver under test, so as to test the hardware functions of each yaw driver under test. The integrated control module includes a communication function test unit and an acquisition function test unit , brake circuit control function test unit, motor speed control function test unit and motor torque control function test unit.

The invention relates to an automatic testing system for yaw drivers, and belongs to the technical field of wind power generation equipment. The testing system comprises at least one testing unit andan integrated control module, wherein the testing unit comprises a first motor and a second motor, the first motor is in shaft connection with the second motor, the first motor is used for being controlled by the first tested yaw driver, the second motor is used for being controlled by the second tested yaw driver, the integrated control module is used for being in communication connection with all the tested yaw drivers so as to test the hardware functions of all the tested yaw drivers, the integrated control module is used for controlling each tested yaw driver to execute the corresponding hardware function test according to a hardware function test starting command, receiving feedback information of each tested yaw driver, and making judgement according to the feedback information to realize the hardware function tests. According to the automatic testing system, all the testing units are integrated in the integrated control module, the comprehensive tests of the hardware functions of the yaw drivers are realized, and the delivery quality of the yaw drivers is guaranteed to reach the standard.
Description
technical field [0001] The invention relates to an automatic test system for a yaw drive, belonging to the technical field of wind power generation equipment. Background technique [0002] The wind turbine yaw system is one of the essential components of the horizontal-axis megawatt-scale wind turbine. It has two main functions: (1) to make the wind wheel track the wind direction that changes steadily; (2) when the wind turbine is due to Yaw effect, when the cables connecting the nacelle and the electrical equipment in the tower are torsionally twisted, the cables can be automatically untwisted. The wind turbine yaw control system is a position servo control system in principle. The PLC calculates the angle between the wind and the position of the nacelle through the wind direction signal detected by the wind speed and direction sensor, so as to determine whether it is necessary to adjust the direction of the nacelle and in which direction the adjustment can align with the ...
